Description

The Closed System Freemie Barriers (2) for use with Closed System Freemie Collection Cups.

NOTE: These parts are very durable, and unless damaged, torn or lost are not likely to wear out while you are pumping. If you are experiencing a loss of suction, be sure to follow the proper assembly instructions; place or seat this barrier onto the funnel first, then slide the closed system valve base over this barrier, and press firmly to achieve a good seal.
